Constructor.
Runs the process.
The callback receives the type of output (out or err) and some bytes from the output in real-time. It allows to have feedback from the independent process during execution.
The STDOUT and STDERR are also available after the process is finished via the getOutput() and getErrorOutput() methods.
Runs the process.
This is identical to run() except that an exception is thrown if the process exits with a non-zero exit code.
Starts the process and returns after writing the input to STDIN.
This method blocks until all STDIN data is sent to the process then it returns while the process runs in the background.
The termination of the process can be awaited with wait().
The callback receives the type of output (out or err) and some bytes from the output in real-time while writing the standard input to the process. It allows to have feedback from the independent process during execution. If there is no callback passed, the wait() method can be called with true as a second parameter then the callback will get all data occurred in (and since) the start call.
Restarts the process.
Be warned that the process is cloned before being started.
Waits for the process to terminate.
The callback receives the type of output (out or err) and some bytes from the output in real-time while writing the standard input to the process. It allows to have feedback from the independent process during execution.
Returns the Pid (process identifier), if applicable.
Sends a POSIX signal to the process.
Disables fetching output and error output from the underlying process.
Enables fetching output and error output from the underlying process.
Returns true in case the output is disabled, false otherwise.
Returns the current output of the process (STDOUT).
Returns the output incrementally.
In comparison with the getOutput method which always return the whole output, this one returns the new output since the last call.
Clears the process output.
Returns the current error output of the process (STDERR).
Returns the errorOutput incrementally.
In comparison with the getErrorOutput method which always return the whole error output, this one returns the new error output since the last call.
Clears the process output.
Returns the exit code returned by the process.
Returns a string representation for the exit code returned by the process.
This method relies on the Unix exit code status standardization and might not be relevant for other operating systems.
Checks if the process ended successfully.
Returns true if the child process has been terminated by an uncaught signal.
It always returns false on Windows.
Returns the number of the signal that caused the child process to terminate its execution.
It is only meaningful if hasBeenSignaled() returns true.
Returns true if the child process has been stopped by a signal.
It always returns false on Windows.
Returns the number of the signal that caused the child process to stop its execution.
It is only meaningful if hasBeenStopped() returns true.
Checks if the process is currently running.
Checks if the process has been started with no regard to the current state.
Checks if the process is terminated.
Gets the process status.
The status is one of: ready, started, terminated.
Stops the process.
Adds a line to the STDOUT stream.
Adds a line to the STDERR stream.
Gets the command line to be executed.
Sets the command line to be executed.
Gets the process timeout (max.
runtime).
Gets the process idle timeout (max.
time since last output).
Sets the process timeout (max.
runtime).
To disable the timeout, set this value to null.
Sets the process idle timeout (max.
time since last output).
To disable the timeout, set this value to null.
Enables or disables the TTY mode.
Checks if the TTY mode is enabled.
Sets PTY mode.
Returns PTY state.
Gets the working directory.
Sets the current working directory.
Gets the environment variables.
Sets the environment variables.
An environment variable value should be a string. If it is an array, the variable is ignored.
That happens in PHP when 'argv' is registered into the $_ENV array for instance.
Gets the contents of STDIN.
Gets the Process input.
Sets the contents of STDIN.
Sets the input.
This content will be passed to the underlying process standard input.
Gets the options for proc_open.
Sets the options for proc_open.
Gets whether or not Windows compatibility is enabled.
This is true by default.
Sets whether or not Windows compatibility is enabled.
Returns whether sigchild compatibility mode is activated or not.
Activates sigchild compatibility mode.
Sigchild compatibility mode is required to get the exit code and determine the success of a process when PHP has been compiled with the --enable-sigchild option
Performs a check between the timeout definition and the time the process started.
In case you run a background process (with the start method), you should trigger this method regularly to ensure the process timeout
Returns whether PTY is supported on the current operating system.
Sets the path to the PHP binary to use.
